After every second battle we both get stuck on the loading screen when it’s returning us to the campaign map. Only way out is force the game to close. Upon reloading and fighting the battle again it would complete successfully, but then the subsequent battle will lock up after it finishes. Rinse and repeat.

The Imperial coop campaign gets stuck on the loading screen after every second battle. The game music continues to play and can be muted with the 'M' key, task manager doesn't consider the game to be unresponsive but the loading screen simply won't go away.

We both have to alt + f4 the game, reload the save before the battle, fight the battle then save again. We then find the next battle then has the same issue.

We've yet to test fighting a battle then save, reload the new save, then fight the next battle.
